Focal Kanta No. 2 Speakers hum with speaker with speaker cable disconnected
Thanks Erik for clearing up the mix-up. The measurements quoted above are the amp’s DC offset, I chose the right speaker binding posts but the left should be the same, no? I’ll try again when I get a new meter. Forgot to ask what’s an acceptable r...

Sorry Eric, the timeline of the posts have me answering in reverse order. If I un-short the speaker the hum comes back, whether in the listening room or elsewhere, doesn't matter. If it's EMF and a wonky something in that speaker only, then yeah ...

@mofojo the hum is independent of the phono. I did unplug the phono’s power and umbilical cord, so zero power. I think this hum is what’s causing the phono to hum in the first place. @erik_squires Thanks Erik! I give it a try. @gs5556 You might ... 
Focal Kanta No. 2 Speakers hum with speaker with speaker cable disconnected
Thanks for the suggestion, no home alarm either. It’s specifically the left speaker, even with no speaker cable connected. It being the left speaker makes it a bigger issue, as it’s closest to the analog setup. So any noise generated by the speak...

Thanks for the reply... No there isn't any in close proximity to the house.
